est and Large-Group Awareness Seminars: Arising out of the human potential movement in the 1960s were a number of workshops, seminars and training programs. The most famous human potential program was erhard seminars training known as est. est was an intensive 60-hour workshop designed to alter a person's life view. There are a number of est clones including Life Spring, Actualizations and Forum, which is a successor to est. All of these workshops have several features in common. Participants are verbally attacked. The idea is to break down emotional defenses in order to allow new beliefs and attitudes to take over. There is a significant cathartic element in that emotional release is generated by the est techniques.

Both est and Landmark Forum could be classified as LGATs (large group awareness trainings), a sociological grouping that includes neuro-linguistic programming, Insight Training Seminars (see the Movement of Spiritual Inner Awareness), and a whole plethora of sales and motivational courses.

Landmark Education, as it's formally known, is hardly alone. There are any number of groups that foster change in an intense, supportive environment. Formally, they are gathered under the rubric 'large group awareness training.' A few groups are relatively new. Some have been around for decades. Almost all owe a major debt to a Unity minister named Alexander Everett.

More direct evidence comes from a careful study of Large Group Awareness Training programs, variously known as Erhard Seminars Training (est), Lifespring, or simply the Forum. The basic procedure of these courses parallels the group training workshops ... but the emphasis shifts from group effectiveness to personal development. By talking through life challenges, aspirations, fears, and the like with fellow participants and professional counselors/teachers, individuals hope to change how they view themselves, their family and friends, and their prospects for a fulfilling life.

A large group awareness training (LGAT) program is a personal development training program in which dozens to hundreds of people are given several hours to several days of intense instruction aimed at helping participants begin to discover what is hindering them from achieving their full potential and living more satisfied lives.
